A content analysis of bizarreness was carried out in order to separate
different dream contents from each other and to report the occurrence
of bizarreness across these contents. All expressions describing one
of 14 contents (Self Place, Time, Persons, Animals Body Parts, Plants,
Objects, Events, Actions, Language, Cognition, Emotions, Sensory Expe
riences) in 32 female students' home-based dream diaries were scored.
Each element was categorized as Non-bizarre or Bizarre (Incongruous, V
ague, Discontinuous). The results show that bizarreness is not randoml
y distributed across different dream contents and that distinct types
of bizarreness show a dissimilar pattern of distribution. Language and
Cognition are the most and Self is the feast Incongruous content. Pla
ce is high on both Discontinuity and Vagueness. We suggest that an ade
quate baseline for what is bizarre in dreams is the subject's personal
waking reality, and for the proportion of bizarreness, the amount of
comparable non-bizarre dream elements.
